Does whitening ruin enamel? Is charcoal toothpaste safe? Our cosmetic team sets the record straight.
Whitening is the most-requested cosmetic treatment we offer — and the one surrounded by the most misinformation.
Myth: whitening weakens enamel
Professional peroxide gels pass through enamel to break down stain molecules; they don't dissolve the enamel structure.
Myth: charcoal is a natural whitener
Charcoal is abrasive. It can polish away surface stain but also scratches enamel, which makes teeth look more yellow over time.
Myth: results are permanent
Results last one to three years depending on diet and habits. Custom trays make top-ups quick and inexpensive.
